GB/T 19954.1-2016

This part of GB/T 19554 specifies the limits and measurement methods for the equipment described in the scope of application, involving requirements for continuous and transient disturbances, conducted and radiated disturbances. These requirements are essential for electromagnetic compatibility. This part applies to professional audio, video, and audio-visual equipment defined in Chapter 3, as well as lighting control equipment for entertainment venues described in Chapter 4, including professional digital equipment defined in Section 3.5 and components specified in Section 7.3. The disturbance signal frequency range specified in this part is 0 Hz to 400 GHz, but requirements are not set for the entire frequency band. See Note 2. Appendix E provides information on infrared transmitters with wavelengths of 0.7 μm to 1.6 μm. This part does not consider the conditions of failure of disturbance sources or disturbed equipment. The equipment defined in Sections 3.4, 3.5, and 3.6 can operate under any form of power supply, including: -- public low-voltage grids; -- independent grids with similar characteristics; -- DC power supplies for specific equipment; -- built-in batteries in the equipment; -- backup generators, etc. Some standards referenced in this part may not apply to independent low-voltage grids.
